LIGHTING DEVICE FOR OVENS.

Specification of Letters Patent.

Application filed September 24, 1913.

Patented Mar. 10, 1914.

Serial No. 791,604.

To all whom it may concern Be it known that I, ADOLPH StissLIN, a citizen of the United States, residing at Gulfport, in the county of Harrison and State of Mississippi, have invented new and useful Improvements in Lighting Devices for Ovens, of which the following is a specification.

This invention relates to lighting devices for bakers ovens, the object of the invention being to provide an illuminating device which is operable by simply opening and closing the oven door, the light being thrown into operation upon opening the oven door and being extinguished immediately the oven door is moved to its closed position, thereby greatly economizing in the use of the electric current used to energize the lamp which furnishes the light for illuminating the interior of the oven.

lVith the above and other objects in view, the invention consists in the construction, combination and arrangement of parts, as will hereinafter be more fully described, illustrated and claimed.

In the accompanying drawings :-Figure 1 is a view in elevation of an oven, showing the oven door, the illuminating lamp, and the lamp controlling switch in its relation to the operating handle of the door. Fig. 2 is a perspective view of a portion of the oven showing the switch and oven door handle and their connection and relation to each other.

Referring to the drawings 1 designates an oven and 2 the oven door which is swung from a horizontal shaft 3 extending along the top edge of the door and journaled at the point 1 in suitable bearings. One end of the shaft 8 is extended into a recess 5 formed in the masonry or front wall of the oven where said shaft is provided with an operating handle or lever 6 which, when the door 2 is closed, stands in an upright position as shown in Fig. 1.

7 designates an electric lamp which is arranged in a recess 8 in the front wall of the furnace and in front of a transparent panel 9 looking toward the oven space.

10 designates a lamp controlling switch which is mounted to turn in bearings 11 on a switch board 12 arranged close to the oven door operating handle 6 as shown in Figs. 1

and 2. This switch embodies an arm 13 which is adapted to be inserted between a pair of oppositely located contact points 1 1 on the switch boa rd 19, the points 1 1 and the switch 10 being connected by circuit wires 15 and 16 which lead through a suitable bat tery (not shown) to the terminals of the electric lamp 7 above referred to. The switch 10 is also provided with an operating lever arm or extension 17 which is connected by means of a chain 18 to the oven door operating handle (3, the lever arm 17 extending behind the arm (3 so that when said last named arm is pushed inwardly to close the oven door it pushes the arm 17 inward and thereby moves the arm 13 of the switch outwardly from between the contact points 14 thus breaking the circuit and extinguishing the lamp 7. lVhcn the oven door 2 is moved to its open position by pulling outwardly on the handle (3, the chain 18 pulls the arm 17 of the switch outwardly and moves the arm 13 between the contact points 1 lthus closing the circuit and energizing the lamp 7.

The device hereinabovc described will be found of great convenience in use and very economical in the consumption of the electrical current as the current is in use only as long as the oven door is kept open to inspect the contents of the oven or to place the bread therein and remove the same therefrom. The device will avoid the inclination on the part of employees to leave the lights burning most of the time when they are not needed.

lVhat I claim is The combination with an oven door, and a shaft forming the axis of movement of the door and on which said door is fastened, of an operating lever on one end of said shaft, a switch arranged adjacent to said lc ver and provided with an operating arm which lies behind the operating lover of the oven door, a slack flexible connection between said operating lever and said arm, and an electric lamp in circuit with and controlled by said switch.

In testimony whereof I atlix my signature in presence of two witnesses.
